H.crx-si

If I put a d16z6 into a 1 89 crx si running the z6 ecu will it automatically allow vtec to engage or do I need to run it off another source ie. rpm switch? Also what kinda times do you guys in your crxes run with z6's equipped with I/H/E?


Sorry guys ment to put this into the crx forum Im drunk and clicked the wrong forum
